Answer 2

Answer:

10

Step-by-step explanation:

x=5+2root6

so, 1/x = 1

5+2root6

= 1 ×(x-2root6) (I have just

5+2root6×(5-2root6) rationalized it)

= 5-2root6 (here if u see, 5 and

( 5)²-(2root6)² 2root6, then they are

in theform of

(a+b)×(a-b),which is

a²-b²)

=5-2root6

25-24

1/x =5-2root6

now, x+1/×

= (5+2root6)+(5-2root6)

=5+5+2root6-2root6 (+2root6 &

-2root6 are

canceled)

=5+5

=10
